No. 12/147,397, filed Jun. 26, 2008, and U.S. ProvisionalApplication No. 60/981,625, filed Oct. 22, 2007, and U.S. ProvisionalApplication No. 60/981,632, filed Oct. 22, 2007, all of which areincorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to compositions, kits and methods fortreating hair. More particularly, the present invention includescompositions, kits and methods for treating hair using compoundsdescribed below, but without agents for effecting polymerization. Theinventive compositions, kits and methods may also be used on hair otherthan on the scalp. In addition, the inventive compositions, kits andmethods may be used on animals other than humans, including on the hairor fur of domesticated animals, including on cats and dogs.

2. Background of the Invention

The hair care industry is a multi-billion dollar industry in the UnitedStates alone. The industry includes the development, production, andmarketing of a large array of products for hair care, includingshampoos, gels, mousses, lotions, sprays, conditioners, coloringproducts, pomades, serums, waxes, and repair products. Most of theseproducts utilize pre-formed polymers developed to impart a desiredcharacteristic upon application to a user's hair. For example, polymersare used to give hair shine, style hair, preserve hair style, give haira desired texture or feel, enhance hair color, condition hair, dry hairso it sets quickly, straighten or smoothen hair, soften hair, strengthenhair, make hard-to-treat hair manageable, enhance optical properties,provide hold to hair, provide frizz control and/or to repair damagedhair.

Existing hair care treatments, however, suffer from numerouslimitations. One problem common to many hair care products is poorefficacy and longevity. For example, existing hair care treatments arenot robust and can lose their efficacy over the course of a day. Manytreatments lose their efficacy upon exposure to water or excesshumidity. In addition, many hair treatments weigh down hair, flake off,leave unsightly residues, fail to dry and set quickly, do not provideadequate hold, and are not effective for hard-to-treat hair (e.g.,naturally curly hair). Treatments have been developed which overcomesome of these issues; however, they typically involve permanentlytreating the hair with reducing and/or oxidizing agents which can damagehair. Thus, there remains a need for hair treatments that withstand therigors of a typical user's daily routine and can maintain efficacy in avariety of environments without damaging hair fibers. In addition, haircare products which are designed to protect hair or deliver agents whichimprove hair strength, shine, color, and arrangement suffer from similarlimitations as they also exhibit poor efficacy and longevity requiringdaily application. It is preferable that a hair treatment be longlasting, not weigh down hair, not flake, and not leave any undesirableresidues. Furthermore, the hair treatment should preferably dry and setrelatively quickly, provide adequate hold, and be able to managehard-to-treat hair.

Active Hair Care Ingredients

A variety of active hair care ingredients may be used in the inventivecosmetic hair care compositions. A variety of chemical compounds may beused in accordance with the present invention to treat hair. In certainembodiments, the compounds are small molecules. In certain particularembodiments, the compounds are small organic molecules. In certainparticular embodiments, the compounds are fluorinated, small organicmolecules. In certain particular embodiments, the compounds arenon-fluorinated, small organic molecules. In certain particularembodiments, the compounds are chlorinated, small organic molecules.Combinations of compounds may be used to treat hair, thereby creatingdifferent cosmetic effects. The availability of a wide range ofcompounds also allows for treating hair to achieve various desiredproperties, including: (1) controlling moisture penetration into thehair (frizz control), (2) providing a soft feel to the hair, without aharsh feeling (conditioning), (3) increasing the shine of the hair, (4)enhancing the hair's color, (5) avoiding the feeling of stickiness tothe hair (and consequently resisting accumulation of dirt to the hair),(6) dries and sets quickly, (7) can help generate and or preserve thestyle of the hair, (8) adding strength to the hair, (9) leaving a lowamount of residue (are “weightless”), (10) do not flake off the hair,(11) lasting over the course of more than one day, even more than 5days, (12) affecting, including reducing, the surface energy of the hair(and thereby affording quicker drying of hair), (13) affordingmanageability for hard-to-treat hair, as well as repairing damaged hair,(14) providing hold, and (15) providing shape.

Some of the above-identified beneficial attributes have been afforded inexisting hair care products through use of compositions containingconditioning agents such as silicones or other polymers, which have ahigh affinity for keratin and especially for the hair on the scalp. Suchcompounds include, but are not limited to silicones such ascyclomethicone, dimethiconol, dimethicone, cyclopentasiloxane,cyclomethicone, trimethylsiloxyphenyl, dimethiconol, cyclopentasiloxanedimethicone copolyol. However, the coating on keratin fibers, such asthe hair, obtained with such compositions often has an unpleasant tackyfeel and also may be readily lost via transfer, for example when a handis passed through the hair. In addition, as a result of such transferthe hair may give the impression of being dirty, sticky or tacky. Also,the effects of the use of such silicone compounds and polymers is notlong lasting as they are removed by shampooing the hair, thus making itnecessary to repeat application of the compositions to the hair, forexample, after rinsing, washing or shampooing. Moreover, residue fromsilicone compounds may build up on the hair and contribute to making thehair limp, contribute to worsening frizz and when used with heatappliances silicone containing compositions may cause “silicone burn.”

The inventive compositions and methods therefore afford the benefits ofsilicone containing composition without many of their drawbacks.Accordingly, the compositions, methods of the invention preferably donot employ a compound containing a silicone compound; preferably thecompositions, methods employ less than 10% wt/vol of such a siliconecompound, preferably less than 1% wt/vol of such a silicone compound,more preferably below 0.5% wt/vol, more preferably below 0.2% wt/vol;more preferably below 0.1% wt/vol; more preferably below 0.05% wt/vol;more preferably below 0.01% wt/vol; and still more preferably below0.001% wt/vol.

Attempts have been made to treat hair with certain acrylate monomers andpolymerize them in situ by free-radical polymerization. For example,U.S. Pat. No. 3,676,550 discloses use of certain acrylate andmethacrylate compositions as hair treatments. The acrylate andmethacrylate monomers employed in U.S. Pat. No. 3,676,550 do not readilypolymerize in the presence of moisture. Indeed, those compositionsemploy an “inert solvent” (which contain 10 to 90% water; the remainderbeing water-miscible organic solvent).

Unfortunately, compositions and methods that employ in situ free radicalpolymerization tend to degrade the hair, probably since harsh chemicalsare involved. Another problem reported for such compositions and methodsis that the chemicals employed irritate and/or are harmful to the hairand/or skin and leave the hair feeling harsh, as well as causing hairdiscoloration. Furthermore, many such hair treatments may involvereduction of hair prior to treatment, which causes additional hairdamage.

In contrast, the compounds employed in the inventive compositions andmethods are not toxic, are not harmful to the hair or skin and do notleave the hair feeling harsh or cause hair discoloration. Moreover, theinventive compositions and methods do not rely on free-radicalpolymerization agents or pre- or post-treatment of the hair with eithera reducing or oxidizing agent. In certain embodiments, the inventivecompositions and methods do not employ a free radical initiator, apolymerization initiator or a polymerization catalyst. In certainembodiments, the inventive compositions and methods do not employ morethan about 0.001% weight/weight, more preferably not more than about0.01% weight/weight, even more preferably not more than about 0.1%weight/weight of a free radical initiator, a polymerization initiator ora polymerization catalyst. In certain embodiments, there is not morethan approximately 0.001 per mol of a free radical initiator, apolymerization initiator or a polymerization catalyst per mol ofmonomer. Accordingly, the inventive compositions and methods preferablydo not employ more than about 0.001% weight/weight, more preferably notmore than about 0.01% weight/weight, even more preferably not more thanabout 0.1% weight/weight of a peroxide; a peracid, a peroxide generatingsystem; a peroxomono sulfate; a peroxodi sulfate; a diazo compound, aredox catalyst (such as NH₄S₂O₈/NaHSO₃; H₂O/Fe³⁺; S₂O₈ ⁻²/RSH; Fe³⁺/HSO₃⁻; Ce⁺⁴/ROH; KMnO₄/citric acid; sodium sulfite).

One approach to avoid the harsh chemicals and/or conditions involved inin situ polymerization has been to avoid monomers that do not requiresuch initiators, but rather employ monomers that readily polymerize inthe presence of moisture (water). Accordingly, U.S. Pat. No. 5,082,010shows that cyanoacrylates have been used as a treatment for hair.Cyanoacrylate monomers readily polymerize in the presence of moistureand are said to be “instant adhesives.” “Crazy Glue” (2-cyano acrylate)is such an example. In addition, a medical glue, 2-octyl cyanoacrylate,is FDA approved for use as a wound adhesive for use in surgery. Contactwith the moisture in the air, or from a biological fluid or tissue, issufficient for polymerization of such cyanoacrylates.

In contrast, compositions of the present invention employ monomers thatdo not readily polymerize simply by exposing the monomer to moisture,such as by contact of the monomer with moisture from a biological fluidor tissue as for cyanoacrylates. Indeed, the monomers of the presentinvention may be formulated as stable compositions using aqueouscarriers, for example containing greater than 90% water as carrier. Themonomers of the present inventions are not cyanoacrylates.

Use of the inventive compositions are simple and easy. Preferably, theinventive composition is applied to hair that has been just washed. Itis not necessary to completely dry the hair, but rather, the hair may betowel dried, allowing for the hair to remain moist, or even drippingwet. A composition of the invention is applied and worked into the hairfor example, by the use of a comb or brush, after which the hair is blowdried, preferably using heat from a conventional hair drier, even morepreferably, using a heat source below 160° C. and even more preferably,using a heat source below 120° C. In the case of a composition that is acream, it is recommended that the cream be worked into the ends of thehair, after which the composition is worked into the remaining length ofthe hair. It is not necessary, and indeed it is preferable, that therebe no rinsing step after application of the inventive composition to thehair.

Polymerization Initiators

Polymerization is typically effected through use of a polymerizationinitiator. A polymerization initiator may be chosen based on the type ofmonomers being used, the type of initiation (e.g., heat orphotoinitiation), and solubility of initiator in a carrier or otherexcipient. Preferably the present invention does not include apolymerization initiator, more preferably it does not include apolymerization initiator that is activated under ambient or uv light orusing a heat source below 160° C., and even more preferably using a heatsource below 120° C.

The present invention preferably does not include a free radicalinitiator, which forms free radicals upon exposure to light or uponheating. Typically, the initiator decomposes upon heating or exposure toa certain wavelength of light to yield two free radicals that initiatethe polymerization reaction. The free radical generated from theinitiator reacts with an unsaturated functional group (e.g., an alkene,acrylate, or methacrylate functionality) of a monomer thus beginning thechain reaction which results in the formation of the desired fluorinatedpolymer.

The present invention preferably does not include oxygen tolerantpolymerization initiators. Oxygen-tolerant initiators eliminate the needfor an oxygen-free or an oxygen-reduced environment for thepolymerization reaction to take place.

Exemplary oxygentolerant polymerization initiators include 4,4′-azobis(4-cyanovalericacid); 1,1′-azobis(cyclohexanecarbonitrile);2,2′-azobis(2-methylpropionitrile); 2,2′-azo-bis-isobutyronitrile(AIBN); benzoyl peroxide; 2,2-bis(tert-butylperoxy)butane;2,5-bis(tert-butylperoxy)-2,5-dimethylhexane;bis[1-(tert-butylperoxy)-1-methyl ethyl]benzene; tert-butylhydroperoxide; tert-butyl peracetate; tert-butyl peroxide; tert-butylperoxybenzoate; cumene hydroperoxide; dicumyl peroxide; lauroylperoxide; peracetic acid; potassium persulfate;2-hydroxy-2-methyl-phenylpropanone; 2,4,6-trimethylbenzoyldiphenylphosphine oxide; 2,4,6-tri-methyl benzophenone;oligo(2-hydroxy-2-methyl-1-(4-(1-methylvinyl)phenyl)propanone; and4-methylbenzophenone.

The present invention preferably does not include an initiator. Toeffect polymerization typically, the concentration of initiator isapproximately 1000-fold, 100-fold, 10-fold, or 5-fold less than theconcentration of monomer. To effect polymerization in some cases theinitiator is at a concentration of more than about 0.001%. In othercases the initiator is at a concentration of more than about 0.01%. Incertain other cases the concentration of initiator is more than about0.1%.

Moisture Resistance

Moisture on hair and its penetration into the hair can disturb thearrangement of hair proteins, resulting in cosmetically undesiredchanges, such as, an increase of frizz. The present invention provideshair, in particular hair on or from the scalp, with beneficial moistureresistance properties. Moisture resistance in the present inventionrefers to the hysteresis of water sorption/desorption when measured byDynamic Vapor Sorption (DVS). In DVS a sample is placed on amicrobalance exposed to a continuous flow of air with predetermined andconstant relative humidity. As the humid air passes over the sample, azone of constant moisture concentration is created around it. This zoneallows the rapid establishment of water vapor sorption or desorptionequilibrium by maximizing mass transport of water vapor into and out ofthe sample.

Mass changes in the sample (e.g., a swatch of hair) due to water vaporsorption/desorption can be measured between different levels of relativehumidity at a particular temperature. The change in mass can be plottedas a function of the relative humidity, which provides information aboutthe nature of water vapor sorption phase (absorption and/or adsorption)when humidity is increased, or, conversely, the nature of desorption ofwater, when humidity is decreased. The difference in changes in mass atany particular value for relative humidity in the sorption anddesorption phases is known as the hysteresis and can be used as ameasure to evaluate the ability of a hair treatment to resist or controlmoisture on and in hair. As described below, the invention affordsreduced hysteresis especially over relative humidity values range of30-80% RH.

In the context of the present invention, moisture resistance is measuredaccording to DVS Protocol I.

DVS Protocol I

1. 1.50 g of bleached hair tress is dampened with 0.30 mL de-ionizedwater, optionally via pipet, and lightly combed through to remove anytangles.

2. Apply composition to the hair tress according to the followingamounts: for a serum (0.10 g to 0.12 g), for a cream/lotion/mousse (0.20g to 0.25 g), and for a spray (0.35 g to 0.40 g) and is distributedevenly and combed through the hair. Preferably the weight ratio offormulation to hair should be approximately 0.073 for serums, 0.15 for acream/lotion/mousse and 0.25 for a spray.3. Styling consists of 10 passes with a hair brush and blow drier set tohigh, approximately 50-120° C.4. After styling, the hair is cut and sections from the middle of eachtress (approximately 300 mg) are analyzed via DVS.5. DVS conditions are as follows. Unless otherwise stated thetemperature employed is 25° C. Sorption phase: Start at 30% RH andincrease up to 90% RH, each step increasing RH by 10%. Desorption phase:Start at 90% RH and decrease down to 0% RH, each step decreasing RH by10%. At each RH condition, the sample is maintained for 4 hours, and thestep up or down to the next RH level is programmed to occur over 20 minperiod.

Monitoring the hysteresis values from such a DVS experiment on hairsamples allows assessment of the ability of a hair treatment to resistor control moisture.

The present invention affords superior moisture resistance compared toeither (1) a control treatment using water and (2) a leading siliconeproduct, such as Kerastase Olexo Relax Serum®, which in fact increasedthe hysteresis compared to water. Preferably, use of the invention on ahair tress as described above affords a 4% reduction in the averagehysteresis values compared to control (water-treated) hair over therelative humidity range of 30-80% when examined by the DVS protocoldescribed above. More preferably, use of the invention on a hair tressas described above affords more than a 10% reduction and still morepreferably more than a 20% reduction, in the average hysteresis valuescompared to control (water treated) hair over the relative humidityrange of 30-80% when examined by the DVS protocol described above. Evenmore preferably, the invention affords a 50% or more, or even an 80% ormore, reduction in the average hysteresis values compared to control(water-treated) hair over the relative humidity values range of 30-80%RH when determined by the DVS protocol described above.

Weightlessness

Those who use hair care products desire the beneficial effects describedabove. However, such users do not want the feeling of residue/product inor on their hair. A composition that maintains performance, but whichdoes so with less residual weight or “feel” in the hair is, therefore,preferred.

The compositions of the present invention, while maintaining productperformance, beneficially lose no less than 25% of their weight,preferably 50% of their weight, more preferably no less than 70% oftheir weight, still more preferably no less than 80% weight, and stillmore preferably no less than 90%, and most preferably 95% or higher oftheir weight after heating at 55° C. and 25% RH for 20 minutes (forspray formulations) and 30 minutes (cream/lotion/serum/mousse)formulations according to the “Weightlessness Test I.”,

Weightless Test I

Composition is dispensed into an uncovered container and spread outevenly. For instance, the container is a round container with a diameterof 9 cm and a lip measuring 0.5 cm.

1. The containers are labeled and then weighed immediately before andafter dosing with 3 g of formulation.

2. Compositions are left to equilibrate at ambient conditions (25° C.,30% RH) for 5 minutes before placing into the oven.

3. The container is placed into an oven controlled at 55° C. and 25% RH.

4. Each dish is removed and its mass recorded at 20 minutes for spraycompositions and 30 minutes for cream/lotion/serum/mousse compositions.

The compositions for treating hair according to the invention on averageleave at least 25% less residue upon dry-down when following packageinstructions for amounts used for Kerastase Oleo Relax Serum®, JohnFrieda Frizz Ease®, Biosilk Silk Therapy®, Redken Smooth Down HeatGlide®, Nexxus Sleek Memory Straightening Smooth Spray®, Barex Re-defineCrème®, Fekkai Glossing Cream® and Bedhead Curls Rock®. It is believedthat one reason for the “weightlessness” benefits of the inventiveformulations is that they do not require, and preferably do not include,silicone compounds at levels found in the above identified hair careproducts.

Dirt Resistance

Many materials are used to control or reduce moisture penetration intohair fibers. However, the majority of these materials are oil-based orsilicone-based. The resulting effect is modest moisture resistancecombined with a heavy residue feel which attracts grease andparticulates. It is desirable in the art to create a composition thatwill control or reduce moisture penetration into hair fibers whileleaving the hair feeling lightweight, non-greasy, and minimizingattraction of dirt/particulates.

The attraction of dirt and particles to the hair leaves the hair limper,heavier, and duller throughout the day. The ability to resistenvironmental pollutants gives the hair longer lasting style and shine.Accordingly, the ability of the present inventive hair care compositionsto resist dirt accumulation was examined and compared to Kerastase OleoRelax Serum®. Corn starch was selected as simulated dirt. USP cornstarch is uniformly-white and can associate with hair, providingexcellent contrast on black hair, thereby allowing for a quantifiableGray-scale measurement via digital photography. Remaining corn starchwas also assayed by gravimetric analysis.

Starch Resistance (Gravimetric)

The inventive hair care compositions when tested on hair as describedbelow should afford gain in weight of no more than 15% by weight,preferably no more than 10% by weight, more preferably no more than 7%weight, and most preferably no more than 5% by weight when subjected tothe Starch Test I.

Starch Test I

1. 1.50 g of virgin dark brown hair tress is dampened with 0.30 mL ofwater.

2. Apply composition to the hair tress according to the followingamounts: for a serum (0.10 g to 0.12 g), for a cream/lotion/mousse (0.20g to 0.25 g), and for a spray (0.35 g to 0.40 g) and is distributedevenly and combed through the hair. Preferably the weight ratio offormulation to hair should be approximately 0.073 for serums, 0.15 for acream/lotion/mousse and 0.25 for a spray.3. The hair was styled with a hair brush and blow drier on high speedand high temperature, approximately at 50-120° C. for 30 seconds.4. The tress is saturated in a bath of corn starch, for instance, inabout 2 grams of corn starch, USP.5. The tress is removed from the corn starch bath and shaken by handuntil all loose corn starch is removed, for instance, for 10 seconds.6. The tress is weighed and the new mass is recorded.

Starch Resistance (Gray Value)

The inventive hair care compositions when tested on hair as describedbelow should display equal Gray values to those generated by a similarsample treated with water, preferably the composition-treated hairsample should display Gray values 5% less than those generated from asimilar sample treated with water, more preferably thecomposition-treated hair sample should display Gray values 10% less thanthose generated from a similar sample treated with water, and mostpreferably the composition-treated hair sample should display Grayvalues of at least 15% less than those generated from a similar sampletreated with water when subjected to Starch Test II.

Starch Test II

1. 1.50 g of virgin dark brown hair tress is dampened with 0.30 mL ofwater.

2. Apply composition to the hair tress according to the followingamounts: for a serum (0.10 g to 0.12 g), for a cream/lotion/mousse (0.20g to 0.25 g), and for a spray (0.35 g to 0.40 g) and is distributedevenly and combed through the hair. Preferably the weight ratio offormulation to hair should be approximately 0.073 for serums, 0.15 for acream/lotion/mousse and 0.25 for a spray3. The hair was styled with a round brush and blow drier on high speedand high temperature, approximately 50-120° C. for 30 seconds.4. The tress is saturated in a bath of corn starch, for instance, inabout 2 grams of corn starch, USP.5. The tress is removed from the corn starch bath and shaken by handuntil all loose corn starch is removed, for instance, for 10 seconds.6. Samples were taped hanging against a black background7. Photographs were taken from a distance that allowed the entirety ofthe tresses to be captured, approximately 3 feet away.8. Images were analyzed using Image J software (Wayne Rasband, NationalInstitutes of Health, USA). Photographs were converted to Grayscale anda box was drawn wide enough to encompass all tresses. The box height wasadjusted so as to include only the middle third of the tresses, and the“Plot Profile” feature was used to collect gray value data, which wasimported into Microsoft Excel.

The present invention may be used on any animal with hair. The system isparticularly useful for treating human hair. However, the hair or fur ofother mammals may also be treated. For example, the hair or fur ofdomesticated animals such as dogs and cats may be treated using theinventive system. In addition, the hair or fur of test animals such asrodents (e.g., mouse, rat, rabbit, guinea pig, etc.) or primates mayalso be treated. In certain embodiments, hair samples from a human(e.g., hair clippings) or other animals are tested with the presentinvention. Hair or fur samples treated with the present invention areconsidered to be within the scope of the invention. These hair or fursamples comprise compound on the hair or fur. In certain embodiments,the hair is human hair. In other embodiments, the hair is non-humanhair. In certain embodiments, the hair or fur is dog or cat hair or fur.In other embodiments, the hair is rat, mouse, guinea pig, rabbit,gerbil, or primate hair. The hair treatment system of the presentinvention can also be used to treat hair contained in wigs, toupees, andhairpieces.

These and other aspects of the present invention will be furtherappreciated upon consideration of the following Examples, which areintended to illustrate certain particular embodiments of the inventionbut are not intended to limit its scope, as defined by the claims.

EXAMPLES Example 1 Testing of Treated Hair

Tests as described herein may be used to test shine/luster, breakstrength, and hair fiber thickness.

In this example, the measure of the hair's shine/luster is proposed.After applying a composition and curling and brushing a hair sample, thehair would be wound around a cylinder and placed under a lamp thatmimics sunlight. The width of the cone of luster will be measure andcompared with that of a commercial product.

In this example, the measure of the hair's break strength is proposed.Single hair fibers (treated and untreated) can be attached to an Instronwhich will pull at one end of the fiber, breaking the fiber at a certainforce.

In this example, the measure of the hair fiber thickness is proposed.Cross sections of hair fibers (treated and untreated) can be examinedand measured by microscopy.

In this example, the humidity resistance of the treated hair isproposed. This property can be measured by placing the styled hair tressin an atmosphere of high humidity.

In this example, the feel is proposed. The parameters of feel can beassessed for a given material on the hair fiber. Several parameters suchas tack, slip, stiffness, smoothness, grease, and strength can beevaluated by a blind test of experts.
